The document discusses costume ideas for an anime-style thriller. It proposes adopting the traditional Japanese school girl uniform to portray female characters as weak and submissive but with high sex appeal. This look is meant to attract male attention through short skirts, unbuttoned tops, and high socks. Meanwhile, male characters would be portrayed as strong protectors and cool dressers. The goal is to portray female characters as innocent and weak at first, but to ultimately reveal their true strength and intelligence, while male characters confide in the females to solve the school's mystery.
